Red-eyed treefrog embryo hatching

This was recorded at high speed and is slowed down here. The embryo is 5 days old. Note the small [...]twitches and large mouth-gaping movements at the start. Then the egg ruptures and fluid starts to leak out. The embryo moves its nose into the rupture site and pushes its way out.
